LUBRICATOB.

- Application vl'ed January My invention belongs to that general class of devices known as lubricators, and relates more particularly` to a lubricating device' adapted to force or-eed under pressurea measured Quantity of lubricant to 'anv required numberv of points from acommon source of. supply.y More particularly the same relates to alubricating device particularly designed and adaptedfor use on auto- .V mobiles or theclike, `although its use is not v reliable, durable, efcient andsatisfactory. It has particularly as an object the production of a device` that willdeliver a measured quantity of material to a desired number of points from a central point, and in which the delivery to any point is notV reduced owing to any resistanceinthe lines. If there is any resistance or delay of the device to Jfunction promptly in the manner intended, such is disclosed by the delay of the 'foot pedal in returning, whereby acorrection ot the didiculty may be made. Many other. objects and advantages ofthe construction herein shown and described will be k,obvious to those' skilled in the art from Athe disclosures herein given.

To this end my invention Yconsists in the vnovel construction, arrangement and combinat-ion of parts hereinl shown and described, and more particularly pointedV out in the claims. n 'v In the drawings, wherein likereterence characters indicate like or corresponding parts:

Referring to preferred embodiment of my invention is shown, there is provided 'a container of suitable size, shape vand material, and made the drawings, in i-which kthe n up of the desired number of parts secured together in any suitable manner. Theron` tainer shown consists of. theb'ase or bottoni portion l providedwith a lcooperatingportion 2 forming the side walls and 'cov-er, thereby with the base lrproviding achamber 3 for containing lubricant or anyother fluid which it is desired to dispense. The base ,portion l orbottom isisho'wn provided with an upstanding portion L which is of. su'fli-' cient lengthso that it extends up to 'and through rthe top portion 2 asV indicated at 45, the parts rbeingfsecured together by a nut '6,or equivalent means The parts l and 2 are made to fit together more or less closely 'to,preventleakage, gaskets (not shown)k however, being provided between thev parte if soV desired; nIn theconstruction shown in Figures `2,' 3 and lthe part 5 isfformcd tubular as indicated at 7 vand communicates Y` Projecting into the bore`7 is a plunger' y10, aplunger 11 being 'also arrangedinfthe bore 8. n The part `5 is shown providedl with a port 12 through which oil inayflowfinto l the spacefbetween the plungersfld'and 11, the operation being such, as hereinafter de-` scribed, that when plunger l() is depressed the oil between the plungers will causo the' n plunger 1ly to be elevated andvic-e versaYV Arrangedr between the platel 16 anda bracket 18 on part 5 is a spring 17or the equivalent of the desired tension, which tends to force thev plunger 11 tothe position shown in Fig. 4.- and normally maintain" it in that position.

There is provided` a 'plurality of ducts I f 'wells 2l and 22, and these extend to the ex" terior of thecasing as vindicated at 23 andy 24, or in an yequiwalent manner.-. VThese are discharge ports from which extendthe pip* ing or conduits 25, each terminating at a desired point to provide for the delivery o'l' a lubricant or other fluid to whore desired. The number depends, ot course, on the number ot desired delivery points. ris shown, ports or ducts 26 and 27 connect the dur-.e 21 and 22 with the chamber 3. Carried by the plate 16 are the supplemental or :reed plungers 28, the same being pre'lierably secured to the plate in any suitable manner, as tor example, by means ot a threaded extending portion 29 and nuts 36. Tlfie plungers 28 may be of the same length' ort' varied lengths,` as will be hereinafter described, and they may be ot the saineV or varied diameters.

The container is shown 'provided with a drainpOrt which is normally closed by the drain plug 31 and with a lilling inlet `which is normally clsed by the plug rlhe container may be mounted in place in any suitable manner, as shown, by a bracket 3d connected integrally with the base or other part, or otherwise connected therewith.

A variation in construction and the preferred one is shown in Figs. 5, 6 and 7 in which 1--2 represent the container which, in this case, is arranged with apluralit-y, two being shown, of plunger containers 4', and 5 represents a tubular member secuii'ii'ig parts 1 and 2 together. Part E5 also t'orms a carrier for the plunger 10, as well as a guide for the spring and plungerl plate 16'.' As shown two plungersV 11 are employed in this construction, the same being arranged to cooperate with the plate 16 mentioned. ln this case, the spring 17 arrangedA about the pipe 5 between the plate 16 and a stop plate 14 secured to 5. The plungers 28 are secured to the plate and control the t'eeding of the lubricant from the container, as hereinafter described. The plunger casing` 5 is provided with one or more ports 12', and the extended portion 13 on theplate 16 is provided also with ports 19. I have illustrated in detail in Fig. 8 a simple method ot securing the plungers 28 to the plate 16, so that especially close. machine work and laying out is notV essential, as slight variation may be compensated for in assembling. Fig. 7 also shows a variation-in sizes of the plunge'rs. This feature is shown in dotted lines in l* ure 2 at therletthand side and l have also' shown in this figure in dotted lines how Ahe port may be varied in its location.

When the device is installed on an automobile, it is ordinarily placed below the floor boards 35 (see Fig. 1) and adjacent the drivers seat so that it may be conveniently operated. This, however, is merely as a matter of preference and not an essential location. It also has the convenience oit being a more or less central locationin the case of an automobile installation.

Assuming that the device is installed on an automobile with the pipes 25 connected with various points to be lubricated, as tor example the shackle bolts, brake rods, steering knuckles, etc., llexible connections being used wherever found necessary, and the container lilled with a lubricant such as an oil et the desired grade, the apparatus is ready tor lubricating at any desired time. When it is desired to lubricate, the operator depresses the plunger rod 10, and its movement is transmitted to the plunger 11 through the oil between the two plungers sonthat plunger or piston 1l is raised, `compressing spring 17, carrying plate 16 and plungers 26 upwardly. Obviously, a very little pressureon the toot plunger will be required to compress acomparatively heavy spring 17 since the plunger 11 is operated hydrostatically and is of greater varea than the plunger 10. ln tact, Va compa atively slight pressure on the plunger rod 1() is suiiicient to compress a. spring 17, exerting several hundred pounds pressure against the plate 16. As the several plungers Y 28 are raised, a measured quantity ot oil flows below the plu'ngers 26, the quantity de pending upon the length ot' the plunger and the cross-sectional area of the same. Vthen the toot pedal is released, the spring 17 tends to carry the plate 16 downwardly, returning plunger 11` to its normal position, at the same time hydrostaticallyraising the plunger 10. The oil inthe duc-ts 21 and 22 is forced outwardly through the ducts 2li and 24 into the pipes 25, the ports 26 and 27 being closed by the downward'movement ot the plungers. bviously, varying the size ot any ot' the plungers 28 or location of the ports 26 or 27 will vary the discharge so that it is possible to deliver a desiredmeasured .charge ot lubricant to any desired point.

The operation of the preferred construe tion shown 1n Figs. 5, 6 and 7 1s substantially the same.` As the plunger rod 10 is' operi ient. For different types of cars, or for installations with a dilierent number ot lubri eating points, it is only necessary to select a base or bottom portion 1 having the dcsired number otoutlets and feed plungers, all of the other parts ot' the apparatus being similar for different sizes. It is possible, however, to take one with an excess number o'l outlets, remove the plungers 28 in any of them andplug up the unnecessary outlets so that a base with a large number of ports is also suitable for installation where a less number is requiredwithout any machine work or drilling of extra outlets. This plug,- ging of any of the outlets and removal oi `the plungers is siinpleand there will be no leakage inasmuch as there is no pressure in the! container except in the wells m which,

plungers are operating.v This featurey is of great advantage for the devices are applicable in installations where one or more oil Vlines are to be taken oli without requiring aspecial model of device for each particular-v Lclose both kthe inlet and outlet ports, preventing oil from entering the lines or escaping from them.

Vrlhe apparatus has numerous advantages.- A very little pressure on the foot plunger will exert a tremendous [pressure on va clogged line. One push only on the foot plunger is required to'lubricate all points, although, of course, the foot plunger may be operated more than once if desired. A

single ,impulse'on the foot plunger is transformed into a continuous pressure until all clogged lines are free and all points hibricated. The pressure on the foot plunger,

the distance through which it -is exerted,

and the time consumed by the operator areV the same for any operationof the device,

regardless of the resistance in the lines.

Checkvalves or domes are not required in order to maintain a continuous pressure or to measure the oil, thereby preventing loss of pressure and inaccurate measurement. However, check valves if desired may. be employed in any line to `prevent the o il from being drawn back from ya bearing. When the foot plunger reaches the top, the opera.- tor knows that the car has been as it ywill not return` toits original position until all points are oiled, and if it does not return promptly, the operator then knows ,that the car is not being lubricated frey quently enough.

Due toV the continuous pressure, the natural movements of the chassis parts, while driving, Aassist materially in freeing frozen surfaces. It will be particularly noted that in this season the greater the resistance in any oil line, the greater is the pressure applied on the yoil in that line; so that, therefore, ifone `line should become clogged, all the pressure-is a plied on that line and is continuous until tlie ob- Y tioned.

vtainer, into said actuated plunger,

lubricated,

struction is removed. As beforementioned,

the proportions of the parts may be Varied so as to vary the'amount ofoil or pressure .to any desired point relative any other point.y

`The device is arranged for the desired number of discharge ports, andthe portionsAk 4 may be constructed around as indicated at v4() and the Fig. 3. Obviously, the parts secured together in any `equivalent manner to that shown, andthe parts 5 and 4; ar-V ranged at any-'desired point on the base. This depends to a large extent on the num- `the plunger 1l dottedV line in ber of vfeed plungers required inthe device. Y In some ,cases it .is desired to locate the. than centrally.`

lunger l0 at one side rather Vhile only onespring 1 7v is shown, .there may obviously be any desirednumber.

Having thusV described my invention, it is obvious that various immaterial modifications'may be made in the same without despirit of my invention;

parting -from the hence I do vnot wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts land2maybe herein shown and described or uses men- What I claim as new byLetters Patent is: c f 1 l.
